Magic Doping Fractions in High-Temperature Superconductors

Creators

Description

We report hole-doping dependence of the in-plane resistivity ρab in a cuprate superconductor La2-xSrxCuO4, carefully examined using a series of high-quality single crystals. Our detailed measurements find a tendency towards charge ordering at particular rational hole doping fractions of 1/16, 3/32, 1/8, and 3/16. This observation appears to suggest a specific form of charge order and is most consistent with the recent theoretical prediction of the checkerboard-type ordering of the Cooper pairs at rational doping fractions x = (2m + 1)/2n, with integers m and n.
